To all whom 'it mary concern:

Be it known that I, Bnnr O. Timms, a citizen of the United States,residing at New York', in the county of New York and State of New York,have invented certain new and useful I'm'rexxentisxc llllnsfhl'lonkere''vices,o w` teoowinglsa This invention relates to improvements in 1oush-tank operating devices, and the invention has refereneeto amechanism for operating tanks connected to latrme bowls, and especie!!what is known as low down Hush-t The invention relates particularly-t0nnproveniente in the devices shown and described in my United StatesPatent No. 821,002, bearing date May 22, 1906.

The object 'e Vtlle 4invention is to provide en operating mechanism forunseat-lng the flush valve, which is simple, durable und effautive, landwherein the Vcons'tl'uctioiti and t of the parts ere such that the valve'may be operated in a ready manner 2p wthbut ellort on the part of theuser oftheeleset.

A further object is .to provide meam for the movement of the operatinghandle, and also the roe lever which conso trois the opening of the finsvalve; it being a puteular obect to Ineke the present de@ positive-inits operation, endless liable 'to t out of order than an of'the deviceso 'the dass heretofore p @ther feetres and parte of the-invention willbe from Athe detail de'aol tion whch follows, isind by reference to t eOff.

Fig. 4 is an enlarged plan view, artly insection, of the operating parts nsti-ated in Figs. 2 and v3, showing thedisposition and varrangement of the rockingcver, operating-handle andrelated parte, when the same are at rest and the valve closed, asshowninFig. 1.

In the drawing, 2 repasse showing p nts a metallic water tank ncloeedmthm a wooden case 3, and comprises what is commonly known as e low downHush-tank. W'tllin'the tank 2 3, are operetivey dis used a ush vvalve 4with its langer 5 an also a. water nlet valve 6 and a oat 7 nil 'ofwhich pam follow any of the well-known constructions,

and are not specifically included in'the present invention, "for the ofVillustrating the application and operation 'of theim rovedparts." 'in.1,the'ilnsl1valve4is dsed by the. vrhcallav iperhlpwieer 5., Y fo 1iv"rodstand 9,3m otter ro Aving upper en pivot; y

Theing ermleverl 'eurveslnwardly sot'hat'its [be ionedlixeetlyover L ther-Ive 4. pje rt'nrm ofjleveru is so' contrncted in a peeiiar manner, ns shown',and .is provided on its edge case of the tank, preferably above thehighest water level, thc outer end of the rod 2U being operativel f su)ported by an escutcheon '21, securedJ to tllc face of the tank. Theinner end ol rod 20 is provided with an integral cross-har or operatinglever 22, the latter comprising a short arm 23 and a lon f arm 24, eachol said arms being providcil with an inwardlyprojecting pin or stud, as2G and 2T. Both ol' the said pins are arranged to respectively engagethe hearing portions 13 and 14 ol' the lever 11. The disposition andarrangement ol the operating surfaces 13 and 14, and also the engagingpins 26 and 27 ol' the lever 22 are such that when the parts are atrest, as shown in Figs. 1 and 4, and the o erating handle is held bygravity in vertice osition, the engaging studs 26 and 27 are oth inContact with the hearingr surfaces 13 and 14, this being the normalposition of the parts when the valve 4 is closed.

To operate rocking-lever 11 and effect the lifting ofthe plunger to openthe flush valve 4, the operator has the o )tion of swinging the handle19 either to t e left or to the right. If he swings the handle to theleft,

in 26 acting upon bearing surface 13, will lorce the short end ofrocking lever 11 downwardly, and its long end upwardlv in the directionto open the valve, until the said pin encounters the stop-lug 15, whichwill arre'st the further movement of the handle and ico also lever 11,as shown in Fig. 2. lf the o1perator elects to swing the handle 19 to tie right, pin 27 acting upon the hearing surface 14, de resses the siort end, and lifts the long end o lever 11, until pin 27 comes to astop a ainst the lug 16, winch will again raisethe punger the samedistance as before, (see fig. 3).

After the user of the closet has swung the lever 19 in either directionto o en the i'lush valve, as described, he shoul let gq the handle, and,then owing to its construction and arrangement the handle willgravitate to resting position, as shown in Figs. 1 and 4, without anyassistance.

The handle may be located at. the upper right hand corner of the tank,andthe order and disposition of the lever 11, and other o erating partsreversed, and accomplish t e` same results.

It will be noticed that the.ar1n 24 of double lever 22 is-relativelabout twice the length of the arm 23, w lich, owing to the constructionand disposition of the rockin lever 11, renders it possible to tilt thelong end of said lever the same'distance, no matter in which directionthe handle 19 ma be rotated. Under this arrangement the 1andle, lever 11 and` related parts, are permitted s. ositive measured movement ortravel, which is intended to open the Hush valve sufficiently for theproper flushing of the bowl, and at thcsanietinic prevents anycxtrn oruseless actuating ol' thc valve-operating parts. Under the constructionand arrangement oll the operating mechanism shown and described in myformer patent referred to, it was possible for the operator tocompletely rotate the handle and o icrating lever, in either direction,and there Jy lilt the plunger' a greater distance than necessary for thesale and proper operation oi thc flushing inechanism, land thoughtlesschildren or mis chievous persons could readily disarrange or put thesystem out ol' order.

The present invention is intended to cor* rect the defects of the oldsystem of flushtank operating mechanism, to render the4 same morepositive and reliable, and also to increase the wearing lil'e of theworking' parts. rlo that end l find the best service is obtained, andless trouble and disorder to the tank operating mechanism result, whenthe rocking lever 11 is provided with stoplugs 15 and 16, and also wherethe actuating lever 22 is constructed and disposed in the manner shownand described herein.
